Indication

The construction of a traditional current loop for the capture of pressure sensor signals has its pitfalls – especially when not only a signal must be transmitted to the PLC, but also a local indicator has to be integrated. Let's have a look at the example of a …

Is it possible to connect a non-incendive Ex nA digital indicator to an intrinsically safe Ex i sensor in hazardous areas? Very often, signals from pressure sensors that do not have a built-in digital indicator for the measured value are connected to external digital …

The characteristics of the display are an important selection criterion when deciding on a digital indicator. Here, there are different points that must be considered: 1. The number of segments
This concerns the segments used to display the numbers. The more …

The most important customer requirements for an instrument display are: durable, robust, and good readability of the active pressure even from a distance of up to 3 m, even in poor light conditions. Red LED displays are still the most widely used technology in the …

For the pressure transmitter IS-20 with the ignition protection type ia (intrinsically safe) and ATEX approval, the safety-relevant data for SIL applications have been determined and summarized in the additional instructions "safety-related data" (PDF).
These …
